Composition of Matter
Substance is:
What is: a type of matter with a fixed composition that can't be separated by physical means
Solution is:
Homogeneous mixture of particles small enough that they can't be seen with a microscope, will never settle to the bottom of their container
Physical Property is:
Characteristic of a material that you can observe without changing the substance
A Solid is:
Matter with a definite shape and volume
Melting is:
Solid to liquid
Element is:
What is: a substance made up of atoms with same identity
Colloid is:
Type of mixture with particles that are larger than those in solution, but still too light to settle out
Chemical Property is:
Characteristic of a substance that indicates whether it can undergo a certain chemical change
A Liquid is:
Indefinite shape and definite volume
Freezing is:
Liquid to solid
Compound is:
What is: atoms of two or more elements combined
Suspension is:
Heterogeneous mixture containing a liquid in which visible particles settle
Physical Change is:
A change in size, shape or state of matter. Substance doesn't change identity when it undergoes physical change
A Gas is:
Indefinite shape and indefinite volume
Vaporization is:
Liquid to gas
Mixture is:
materials made of two or more substances that can be separated by physical means
The Tyndall Effect is:
Detecting colloids is sometimes difficult so shining a beam of light at colloid will make the light scatter
Chemical Change is:
A change in one substance to another substance that can't be reversed
Plasma is:
High Temperature Gas
Condensation is:
Gas to liquid
The difference between Heterogeneous and Homogeneous is:
What is: Heterogeneous is easily distinguished and Homogeneous is uniformly spread out
An example of each is:
Vinegar: Solution, Milk: Colloid, Italian Dressing: Suspension
An example of each change is:
Melting ice: Physical, Fireworks exploding: Chemical
Kinetic Theory is:
how particles in matter behave
Sublimation is:
Solid to gas
